Relaxation of Structural Units in MD Simulated Silicate Glasses
Original language description
Several simulations of the molten sodium disilicate system at various temperatures were performed by means of the molecular dynamics with pair-wise interactions between ions. The glass structure was described in terms of {Si}mn structural units, where mis the coordination number of silicon and n is the number of bridging oxygen atoms (BO). Equilibrium transformations, reflecting dynamics of the silicate melt, of various {Si}mn units were observed and the elemental transformations were identified. The time-temperature dependence of the decay of {Si}43 units was described as a superposition of the fast and slow processes. The slow process was found to be an Arrhenius-like and was attributed to BO-NBO transitions during the sodium migration.
